That black mist was not a good stubble at first glance, and even in the pitch-black hall, it could be seen clearly.

From the outside, it looked a bit like the black mist wrapped around the trunk of the Black Iron Tree, swirling and entangled, as if it could crush everything in the world.

Bai Zhenyu looked at the black fog for more than a minute before saying: "This fog is a bit like the 'fog of Black Jujube Bay', commonly known as 'murder fog'!" ”

He paused and continued to explain: "I saw in the "Top Ten Unsolved Mysteries of the Wizarding World" published in China that there is a small lake in the deep mountains in the south of China, and it is called Black Jujube Bay because the shore is rich in black dates.

"There is a layer of fog on the Black Date Bay all year round, and as long as wizards and ordinary people inhale the mist there, they will immediately and frantically kill every living creature in their sight.

"If there were no living creatures around, the person who inhaled the mist would commit suicide in the most brutal way.

"The black fog in front of us is very similar to the shape of the 'Black Jujube Bay Mist'."

Hermione said, "I haven't seen a story like this in a book. ”

"Yes," Bai Zhenyu said, "Because the murderous fog is only found in the East."

"If this fog is similar to the 'fog of Black Jujube Bay', then I have solved an unsolved mystery, the 'fog of Black Jujube Bay' stimulates the human spirit, and it will make people murderous and cruel in a short period of time.

"And the 'fog of Black Jujube Bay' is likely to drift out from the spiritual world."

Ron asked, "Is there any way to deal with it?" ”

Bai Zhenyu shook his head: "There are many witchcraft that can dispel the 'fog of Black Jujube Bay', but none of them can be mastered by a little wizard like us. ”

Harry pondered, "If my Edgeworth ...... from above it"

Bai Zhenyu simply interrupted Harry: "I've seen it in the book, don't look at it being lazy now, when it enters its attack range, it will immediately become flexible." ”

After speaking, Bai Zhenyu hugged his arms and thought about countermeasures, Hermione suddenly said: "You can tell me more about its characteristics!" ”

Bai Zhenyu recalled for a moment before saying: "It likes to be close to places where there are creatures, and it is insoluble in water.

"These fogs seem to be very fond of glass containers, and will even burrow into them on their own.

"So they can only store in glass tubes, because only when they 'see' what's outside, they think they're not restricted from moving, otherwise whatever container it is, it will leak slowly, and it's ......"

Hermione suddenly asked, "We can use Transfiguration to conjure up some glass tubes." ”

"Great idea!" Bai Zhenyu clapped his hands, and at this time he admired Hermione's reaction speed a little!

"But what do you want to change?" Harry asked.

Ron tugged at his clothes, "You're not going to take our clothes, are you?" ”

Bai Zhenyu sighed, compared to Hermione, the two of them came from "experience".

Thinking of this, Bai Zhenyu shook his head helplessly, he couldn't blame Harry and Ron, he could only blame Hermione for being too good.

Bai Zhenyu snapped his fingers: "Do you remember the four stone piers in the hall just now?" ”

If you turn them all into glass containers, they should be able to hold the fog in the front hall.

Just do it, Hermione was in charge of the lighting, and Bai Zhenyu and the three boys put down the stone pier first, and then rolled to the door of the second hall.

After four rounds of back and forth, the four stone piers were finally transported to the designated location.

Bai Zhenyu held his staff and said, "First conceive of a glass container in your mind, pay attention to your wrist movements!" There must be an urgent need for terrariums in mind!

"Come, one, two, three, change! One, two, three, change! ”

Turning a stone pier into a glass container of the same volume, although it won't involve too many changes in volume, weight, and other factors, is already far beyond the ability of a first-year wizard.

But now they have no other way but to try again and again.

Bai Zhenyu's transfiguration technique is the best, but the stone pier in front of him also seems to be very disobedient, constantly being pulled by Bai Zhenyu's transfiguration, or getting longer and thinner, or shorter and thicker, but it is always difficult to form.

The stone pier in front of Hermione also began to reshape, while the stone pier in front of Harry and Ron had changed only slightly.

Bai Zhenyu, the class representative of the transformation class, was not given for nothing, and it took more than twenty minutes to finally turn the stone pier in front of him into a glass container with a larger circle.

Hermione's side has also basically taken shape, and at this time Harry and Ron's scumbag physique is revealed, the stone pier in front of Ron has become a stone pillar, and the stone pier in front of Harry has become a stone ball, and it looks a bit like a golden snitch.

Bai Zhenyu said helplessly: "Give me some face for this class, and listen to the class when I take the deformation class in the future." ”

So he took out his wand and helped Harry look like the Golden Snitch stone pier towards the glass container.

Just as Bai Zhenyu was correcting Harry's Transfiguration, he felt that his wand had given him a huge boost!

The main materials of his wand are acacia wood and phoenix feathers, both of which will perform best against magically gifted wizards.

This is the first time that Bai Zhenyu has felt the "bonus" brought by the wand, and it seems to be eager to show his superiority in front of the "wand" of Harry and others.

At this moment, Bai Zhenyu also felt for the first time that he was 100% compatible with the wand in his hand.

It only took three times for the stone "Golden Snitch" in front of Harry to be transformed into a beautiful glass container.

"Cool!" Ron on the side said, "White, how did you do it?" ”

Bai Zhenyu felt that he seemed to have established a deeper connection with the wand, and he said happily: "It's nothing, it's just that you listen to the class well when you are in the transformation class, read more books, read more newspapers, go to bed early and get up early, and exercise more." ”

Hermione, who had also completed the transformation on the other side, shook her head: "White, no wonder Professor McGonagall asked you to be an assistant, you do have a talent for transformation." ”

The compliment from Xueba made Bai Zhenyu very happy: "What nonsense is telling the truth."

"Okay, okay, you guys take a break, and let me change the last one."

When Bai Zhenyu performed the Transfiguration Technique again, he felt a more tacit understanding with his wand.

The wand also seemed to want to show itself, and this time it only took two uses to turn the stone pillar in front of Ron into a glass container.

After the four glass containers were placed in front of Bai Zhenyu and the four little wizards, Hermione cleared her throat: "Remember, the word 'plus' should be long and clear!" ”

The four little wizards waved their wands together: "Yugadim Leviosa!" ”

Four adult waist-slender, half-human-tall glass containers float in front of the four little wizards.

They carefully controlled the glass container, and walked step by step into the room full of "the fog of Black Jujube Bay".

Bai Zhenyu said: "Attention, if these black fogs are unwilling to drill into the glass container, it means that my judgment is wrong, everyone don't care about anything, turn around and run!" ”

Harry, they were getting more and more nervous, and the terrarium floating in front of them shivered a little.

"Steady! Steady! Although Bai Zhenyu said this to others, his palms were a little sweaty.

After walking about six or seven steps forward, the black mist floating in the room seemed to suddenly find Bai Zhenyu and them, and rushed towards them.

The other party was menacing, and Hermione and the other three little wizards did not turn around and run away under great psychological pressure.

Seeing that the black fog was coming closer, and the momentum was terrifying, even Bai Zhenyu, who thought he had a good psychological quality, was a little frightened.

Fortunately, these black mist did not run towards the four little wizards, but burrowed into the four glass bottles.

Bai Zhenyu let out a long sigh of relief: "Hurry up, hurry up, plug the stopper!" ”

Looking at the four jars of black mist on the ground, the four little wizards glanced at each other, and then laughed.

It's their victory!
